COMP Cams has awakened the musclecar sound--and it's nastier than ever! Introducing Thumpr Series cam and lifter kits, a line of cutting-edge hydraulic roller camshafts for engines originally equipped with flat tappet cams. You can expect a substantial power increase without sacrificing reliability or ease of maintenance! The lobe profile and grind characteristics of new Thumpr cams include blending an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap. This maximizes rough-idling tendencies, delivering a seriously aggressive exhaust note without impacting engine power output. Thumpr camshafts are available in a variety of grind profiles, each producing impressive horsepower and torque performance within a different rpm range.
